Application filed July 10, 1883. (No model.)

To all whom it may` concern:

Be it known that I, JOHN B. CRocKEn, of the city and county of St. Louis, and the State of Missouri, have invented certain newA and useful Improvements in Mechanical Movements; and I do declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, and to the lettersA of reference marked thereon, forming a part of this specification.

The nature of my invention consists in a mechanical movement, the object of which is to increase speed in machinery without any material increase of power.4 -This object isattained bya simple device for combining wheels and series of wheels, as illustratedin the anneXed drawings. i Figure 1 is a top elevation of my invention. Fig. 3 is a verticali section of two wheels.

A represents an iron plate pierced with a suiicient number of holes to receive the studs R R R, so as to allow the nuts to be screwed on their ends from `the under side of the plate in such a manner as to hold them rmly in position. The shoulders of the studs form bearings on the plate, and their other ends are prepared to` receive the wheels E E E, and upon which they rest and revolve.. The plate also constitutes a base or foundationV for the straddles B 'B B,T which are firmly atlixed `thereto and form` the bearings for and upon which rests and revolves the shaft C C. The shafts terminate in sharp points in order to throw off the heat produced by friction, thus preventing the journals from ,ever becoming overheated. t

To the shaft C is firmly keyed the wheel D, which gears into' the wheel E. The double ruiter-wheel F is placed loosely upon the shaft and on one side gears into the wheel E, and

on the other side into the wheels G and J,

` which rest and" revolve upon the transverse axle J. This aXle is constructed from the `horizontal arms of the metal cross, the other ceive the shaft C, to which it is: firmly attached. `A second double wheel, the last of this series, is placed loosely on the shaft C,

\ tion-wheel.

ries of wheels to the drum N through the larger wheel M. All the wheels are held in position ley-means of collars made fast to the y shaft.

a b in Fig. 3 represents a vertical section of my new combination-wheelsc represents the cog placed in the center ofthe face of the miter-wheel, andthe smooth surface on both sides of the cog represents the plain disk of a fricd shows the depression and plain surfaces in the corresponding wheel. They mesh into one another similar to theV regular cog-wheel. At the same time the friction on the both margins of the wheel deadens all noise and co-operates with the cogs in producing forward movements to the wheels.

To the wheel D or to the-pulleyQ, the driving-power may be applied, the wheel D, revolving with the shaft, moves wheel E, which in turn moves the double Awheel F in an opposite direction from D. The wheels G and J, which revolve on the transverse axle, (which also forms a movable fulcrum,) gear into the opposite side of F and into one side of the terminal wheel of i the first series. These wheels G and J, traveling on the periphery of the wheels F, give an accelerated motion of three revolutionsv to the terminal wheel of this series. This motion. is connected or transmitted to the next series of wheels by E',

where it again multiplies itself by three, the t wheel K making nine revolutions, andso on ad iantmn. Each added series of'wheels in creases the speed in the geometrical ratio of three, or moves three times faster than the one preceding it.

TheV iron plate on which the two series of `wheels are affixed is firmly bolted to the derrick in order to shoWAone point of its practical application.

Having.; thus fully described my invention,

In testimony that I claim the foregoing I have hereunto set my hand this 10thV day of July, 1o

A. D. 1883. What I claim as new and desire to secure by T. r 5 Letters Patent7 is-7 JOEL B' CROCIXER' The combination of a series of Wheels, as Witnesses: mounted upon shafts C C and transverse shaft ROGER WILLIAMS,

. and bed-plate A, Vsubstantially as set forth. FRANCK H. LOVING.
